A Paver Conveyor System with Adaptive Modes for Multiple Working Conditions

Abstract

The invention discloses a paver material conveying system with multiple working condition adaptation modes. The paver material conveying system comprises a left material conveying hydraulic control system, a right material conveying hydraulic control system and an electric control system, wherein the first proportional electromagnetic reversing valve (401) of the left hydraulic control system is respectively connected with a first logic control valve (201) and a first pressure compensation valve (301); a first overflow valve (101) is connected with the first pressure compensation valve (301); the second proportional electromagnetic reversing valve (402) of the right material conveying hydraulic control system is respectively connected with a second logic control valve (202) and a second pressure compensation valve (302); a second overflow valve (102) is connected with the second pressure compensation valve (302); the electric control system comprises a control console A1 connected with a controller A2, a left material conveying material level sensor B1, a right material conveying material level sensor B2, a left material conveying solenoid valve and a right material conveying solenoid valve. The paver material conveying system has the advantages of simplicity and convenience in control implementation and easiness in operation.

Description

technical field [0001] The invention relates to a paver conveying system with multi-working-condition adaptable modes, belonging to the technical field of construction machinery hydraulic control application. Background technique [0002] At present, in road construction and maintenance construction, paver construction technology has been further improved and widely used with the development of road construction technology. At present, domestic paver multifunctional paver is used for paving stabilized soil and asphalt material. With the high standard requirements of road construction technology, the road surface quality control requirements are becoming more and more stringent. Among them, the conveying device is the most important working device for paver feeding, and its conveying method plays a crucial role in the forming quality of the road surface. important role. When paving stabilized soil materials, due to the poor cohesiveness of the materials, when the materials ...

AI Technical Summary

Problems solved by technology

[0006] The solenoid valves used in the above three inventions are all on-off valves, which can only meet the working conditions of paving stable soil, and cannot achieve uniform and stable material delivery requirements when paving asphalt materials.

The first type requires manual operation, which is inconvenient to control; the second type of reverse is energized and reversible through the solenoid valve, which is easy to control, but it cannot reduce the impact generated when the reversing valve is turned on; the third type adds a two-position four Through the solenoid valve, the electrical control logic is complex and cumbersome
